Yes Eder even i am facing the same issue when i tried yesterday and now even with a new project when you run a node.js module. Someone from dev team can help.

[david_kunz2]

Hi,

Can you please share your package.json file? (in particular the dependencies).
It appears there is a problem with `@sap/fibers` trying to use Python, which is not installed.

Thanks a lot!
Best regards,
David

[mani_ac]

Even I am getting the same issue , fails at python. Yesterday I noticed a build pack has been changed when I tried to deploy ,prompted me to change node version from 8 to 10. I get issue at sap/hana-client module

[former_member615307]

david.kunz2,

This is my package json

{
  "dependencies": {
    "@sap/xsenv": "^2.0.0",
    "@sap/xsjs": "^5.2.0"
  },
  "description": "my description",
  "devDependencies": {
    "@sap/xsjs-test": "^3.0.2"
  },
  "files": [],
  "main": "server.js",
  "name": "xodata",
  "scripts": {
    "start": "node server.js",
    "test": "node testrun.js"
  },
  "engines": {
    "node": "10.x"
  },
  "version": "1.0.0" 
}

[david_kunz2]

Hi,

The problem is `@sap/xsjs` which has a dependency to `@sap/fibers: 4.0.3-0`. The latter causes a problem with Python. Maybe the xsjs colleagues can help out?

Best regards,
David

[former_member330660]

Hello! we have exactly the same error since yesterday, my package.json

{
  "dependencies": {
    "@sap/xsenv": "^2.0.0",
    "@sap/xsjs": "^5.2.0"
  },
  "description": "my description",
  "devDependencies": {
    "@sap/xsjs-test": "^3.0.2"
  },
  "files": [],
  "main": "server.js",
  "name": "nodejs",
  "scripts": {
    "start": "node server.js",
    "test": "node testrun.js"
  },
  "engines": {
    "node": "8.x"
  },
  "version": "1.0.0"
}

[thomas_jung]

You just need to edit the package.json. That's where the version specification that will be used at run or deploy time is stored.

[former_member330660 · Accepted solution]

Hello,

in package.json I changed the node version from 8.x to 10.x, I also removed:

  "devDependencies": {
    "@sap/xsjs-test": "^3.0.2"
  },

and

"test": "node testrun.js"

my package.json looks like this:

{
  "dependencies": {
    "@sap/xsenv": "^2.0.0",
    "@sap/xsjs": "^5.2.0"
  },
  "description": "my description",
  "files": [],
  "main": "server.js",
  "name": "nodejs",
  "scripts": {
    "start": "node server.js"
  },
  "engines": {
    "node": "10.x"
  },
  "version": "1.0.0"
}

after that I managed to build and deploy my application

I believe the python dependency comes from "@ sap / xsjs-test": "^ 3.0.2"

[former_member615307 · Accepted solution]

Wagner,

I had to do the same and It worked.

But I would like to have some reference updates from SAP WEB IDE / LIBRARIES to stay adviced before I could have this problems.

Do someone know?

Thank for your help.

[thomas_jung]

Yes please do update to node version 10. Instead of removing @sap/xsjs-test you can also update to version 3.1.2 or newer. This should address this issue. On a side note for anyone running to similar errors when building a DB module, then be sure to update the package.json in that module to go to @sap/hdi-deploy version 3.11.2 or higher.

[raveeshsaurabh3]

Hi Thomas,

Your inputs helped me. I was struggling for exactly the same issue for last two days. I changed the node version to 10 and version 3.1.2 for @sap/xsjs-test. This solved the issue for me. Can we try fixing this in the generated code so that this unnecessary struggle can be avoided.

My package.json looks like below.

Thanks & Warm Regards

Raveesh

[gregorw]

Hi raveesh.saurabh3,

I would suggest that you file an incident to get this change implemented in the generated code (would be great if you name the tool you're using to generate the code).

Best regards
Gregor

[gregorw]

As you see in the xsjs/CHANGELOG.md the support for Node.js versions 6.x and 8.x was removed. I would suggest opening an incident via the service marketplace to get the issue fixed.

[former_member615307]

Gregor,

I have 10.x Node js version but I got the same error. I had to remove de dev dependencie @sap/xsjs-test of my packge json. Then the error dissapeared.
